WINDING-MACHINE FOR ARTIFICIAL THREADS.

Specification of Letters latent.

Application filed Kay 28, 1912. Serial No. 700,157.

To all whom it may concern Be it known that I, JEAN MANQUAT, a citizen of the French Republic, residingat Villeurbanne, Rhone, in France, have invented certain-new and useful Improvements in Winding-Machines for Artificial Threads, of which the following is a specification.

This invention relates to improvements in winding machines for artificial threads.

In order to increase the production in the spinning of artificial threads it has been customary to employ two bobbins and when one is sufliciently wound the other is rapidly brought into 'action in such a manner that the continuity of the spinning is not disturbed, the inconveniences which mightotherwise result bein prevented. Thisoperation has hitherto een manually efi'ected but however skilled the workman may be a certain diiference between the quality and uantity of the thread on the first and on t e final bobbin is always found, showing that they are not all stopped at the same time and that the peripheral s eed of a full bobbin is greater than that or an empty bobbin for a constant angular speed. Further the aforesaid manually efiected changes occupy a considerable time, a large number vision of one operative.

The object of the present invention is to obviate the said inconveniences and for this purpose the invention consists in a device which allows of simultaneously releasing all the filled bobbins on one side of the machine and immediately engaging all the empty bobbins.

The annexed drawings illustrate by way of example forms of construction of this device.

Figure 1 being a front view, Fig. 2 a cross section, and Fig. 3 a cross section of a modified form of construction.

In Figs. 1 and 2, a represents the bobbins on which the thread is wound. 0, indicates the empty bobbins, b the tank containing the coagulating and fixing substance in which the bobbins are partly immersed; this tank is traversed longitudinally by a rod 0 carried by bearings d and adapted to be axially rotated by meansof a handle or lever e.

Between each pair of bobbins a and a superg mounted onthe rod 0 and turning with it when the handle 6 is operated, engage between the limbs of the diflerent plates f.

The glass rings or guides h which the difi'erent threads i 2' traverse, are carried on a beam 7' adapted to be given longitudinal movement (by means not shown) for, about the distance which separates the axes of the difierent bobbins-and also a transverse reciprocating movement b means of supports k in order to produce t e usual winding.

The operation of the devicev is as follows :The glass rings it being in the position shown in full lines in Fig. 1, the bobbins a are Winding while the bobbins a are stationary. When said bobbins a are com pletely wound, the bobbins a are brought into action, whereupon the knives 9 being raised to the position shown in full lines, the beam 9" is displaced from right to left Patented July 15, 1913.

in the direction of the arrows Fig. 1, so as to conduct the guides h to the position 72. shown in broken lines in Fig. 1. If at this moment the knives g are lowered by moving the lever e into position 6 (Fig. 2) the said knives are introduced between the limbs of the plates 7 as shown in position g (Fig. 2) and will cut or break the threads '5 which are thus brought into contact with the bobbins a to whichthey adhere and are wound by said bobbins in the same manner as they were previously wound on the bobbins a. When said bobbins a are filled, the reverse procedure to that described takes place by shifting the beam 7' from left to right.

The number of bobbins and consequently etc., can be in accordance with the size of the machine to applied.

In the construction shown in Fig. 3, the rod 0 is arranged at a higher level than in Figs. 1 and 2, and the plates f ofFigs. 1 and 2 are dispensed with, these plates not being absolutely necessary to the success of the operation described.

, What I claim as my invention and desire to secure by Letters Patent 0f the United States is 1. In a winding machine for artificial threads, the combination with a pair of bobbins mounted for axial rotation, of a reciprocating thread guide movable in the di-' reotion of its length and parallel to a line connecting the axes of said bobbins and a which the present device, is

knife located between the bobbins and adapted to sever the thread between the guide and bobbins.

2. In a winding machine for artificial threads, the combination with a pair of bobbins mounted for axial rotation and a thread guide mounted adjacent said bobbins, of a reciprocating, support for said guide movable in the direction of its length and parallel to a line connecting the axes of said bobbins, and transversely thereto, and a knife located between the bobbins and adapted to sever the thread between the guide and either of the bobbins.

3. In a winding machine for artificial threads, the combination with a plurality of pairs of bobbins mounted for axial rotation, of a thread guide for each pair of bobbins movable parallel to a line connecting the axes of said bobbins, a knife for each pair of bobbins adapted to sever the thread between the guide and either bobbin ofa pair and means for actuating all said knives simultaneously.

4. In a winding machine for artificial threads, the combination with a plurality of pairs of bobbins mounted for axial rotation and a thread'guide for each pair of bobbins, of a support carrying all said guides and movable parallel to a line connecting the axes of said bobbins and transversely thereto, a knife located between each pair of bobbins adapted to sever the thread between the guide and either bobbin of a pair and means formanually actuating all said knives simultaneously.

In witness whereof I have signed this specification in the presence of two witnesses.
